Recently, various home appliances are inter connected in wired/wireless network to provide a single service, but their interfaces are not uniformly integrated. In order to get a service in such an environment, users have to figure out how to control each appliance and the way of combining its functions with others. Even worse to the users, many buttons are barely used to control the complicated functions of the appliances on the remote controllers, and controllers have very similar shapes in each other. In this paper, based on the definitions of a task as a unit of services provided in the environment of multi-connected appliances, we propose a markup language for home appliances, called HAML (Home Appliance Markup Language), for generating task-based user interfaces to help controlling multi-connected appliances as one pleases. The proposed method generates interfaces by gathering the buttons frequently used and necessary for tasks, and provides automatic settings of multi-connected appliances. The proposed method is verified with an analysis of scenarios and usability tests.

The aim of this document is to evaluate the effect of bite balance on physical fitness and motor capacity to determine the importance of the occlusal stability as a possible action mechanism of occlusal appliance including mouthguards on physical performances. We all remember that day when the prominent athlete was in the news wearing a mouthguard to improve human athletic performance. I once had investigated the determinants of athletic performance in all sorts of sports. Most of the studies had overinterpretation of results and lack of evidence to support the information. However, I discovered great expectations for new possibility in this field and settled for a more academic approach to this intriguing subject. The followings are some examples of the subject 1. Archers who wore occlusal appliances to increase the vertical dimension of occlusion by 2~3mm increased their ability to focus and to maintain good sense of balance. Their accuracy rate has been improved. The appliance was made of acrylic resin (a type of plastic). 2. Canoe players who wore occlusal appliances to increase the vertical dimension of occlusion by 5mm surpassed longtime competitor and won the race with 10 seconds gap. 3. A cycle rider who wore an occlusal appliance to treat his malocclusion surpassed his old record from 10.8 seconds to 10.3 seconds. His muscle reflexes (anaerobic exercise) and endurance (aerobic exercise) has been enhanced. 4. Occlusal appliances had a good effect on athletic performance in most sports such as swimming, diving, and weightlifting. As for the clenching on dentition, people clench their teeth when they push their physical and mental limits during sports activities. Clenching can be induced by physical exertion when maximum muscle strength is retained and this is similarly found in different types of exercises. In addition, restraint of respiratory function is observed. Therefore, creating a occlusal balance with occlusal appliance or mouthguard promoted a favorable influence when an athlete clenches.

The Smart Home or intelligent home network control system has the need for home devices to cooperate for the purpose of providing the automated services to residents. The cooperation of home devices can be defined as the service for residents that it controls simultaneously two or more home devices with the same purpose about user's control request of specific home device. A object of home device cooperation are the function object of home device, it is well defined in each device model in AHAM(Association of Home Appliance Manufactures) nth(Connected Home Appliances). AMAM CHA is to promote new appliance services and features enabled through networking by describing generic appliance models, objects, and high-level messages, but does not consider the description and process of cooperation between objects of each device model. This paper defines the cooperation relationship that could be discovered in among home devices, and proposes the cooperation model that AHAM objects could process the cooperation relationship.

From the digital perspective, customer journey and customer experience management are emerging as important issues for companies. While digital customer experience has become more important due to the recent surge in online sales of the home appliance products, customers' experience in online is not differentiated as offline-focused traditional methods are maintained. This study aims to analyze the characteristics and mutual influences of customer experiences at each stage of online purchase journey, and to explore the effects on the product repurchase intention, focusing on online purchasers of home appliance which are high-involvement products. As a result, both cognitive and affective experiences of the research phase directly affect satisfaction, whereas affective experience at the purchasing stage indicated indirect effects through cognitive experience. The experience of the research phase positively affects the next phase, the purchasing experience, and the experience of the purchasing phase leads to the intention to repurchase the product. However, it is also found that, depending on the choice of online channels, the experience of research phase may affect the product repurchase intention than the purchase experience.

A Power Management System(PMS), which provides the functions of automatic detection and cutoff of home appliances' standby power without user intervention, is presented in this paper. A client in this system measures the power consumption of a home appliance plugged in it and transmits the information to a server in real-time over a wireless network. The server analyzes the features of the power consumption of home appliances and detects if any home appliance consumes standby power. The detected standby power information is used to create the information of the home appliance and to build a database, which will finally offer the automatic detection and cutoff of the standby power without any configuration through user intervention.

홈네트워크 환경에서 정보가전기기를 제어하는데 PLC(전력선통신)나 IR컬트롤러가 사용된다. PLC의 경우 가전기기동작이 명확하지만 IR컨트롤러 같은 경우에는 방향이나 여러 조건에 따라 가전기기동작이 불분명하여 사용자의 명령대로 수행되지 못하는 경우가 발생한다. 본 논문에서는 이러한 상황을 해결하기 위해 가전기가의 상태를 모니터링하여 사용자에게 알려주는 방법을 제안하였다. 동작 상태와 대기 상태의 전류량이 다른점을 이용하여 동작 여부를 판별한다. 제안된 방법을 사용하면 IR 컨트롤러로 동작하는 가전기기의 상태 신뢰성 을 높일 수 있다.

본 연구에서는 백색가전 제품의 특성에 맞는 임베디드 시스템 플랫폼 디자인을 제안한다. 프로세서는 최근 더욱 각광을 받고 있는 ARM 계열의 디바이스를 사용하였으며 운영체제는 임베디드 시장에서 급부상하고 있는 리눅스를 대상으로 한다. 본 연구는 백색가전 제품군 전체를 대상으로 하고 전자레인지를 이용하여 시제품을 구현하였다. 특히 백색가전은 제품의 특성상 제조원가에 민감한 제품이므로 메모리 등 시스템의 자원 사용을 최소화하여 제조원가를 낮추는 방향으로 디자인의 방향을 정해야 한다. 하드웨어 비용은 현실적으로 거의 시장에서 정해진 비용의 범주를 크게 벋어나지 못하겠으나 소프트웨어의 크기는 접근하는 방법에 따라 차이가 날 수 있다. 이에 본 논문은 가능한 탑재될 리눅스의 커널 크기를 줄이며 파일시스템 및 기타 라이브러리의 크기를 최소화하여 백색가전에 적합한 플랫폼을 제시하는데 주목적이 있다.
